Greetings -
I have a six month old marine tank. 220g. 6 ft long.
Pure radion xr15 lighting basically 1 light per 2 square feet. Lights approx 8 in off water.
reef octo 202s protein skimmer
2x mp40s set to lower flow
Brs old gen 25W UV sterilizer
Filter sock/marine pure block - can’t get anything to grow in fuge.
Started fresh with dry rock/never wet reefsaver
Will link icp test results.
1.026
450 calc
1320 mag
7.5 - 8 alk
78 deg
safe nitrate/phos
I feed once a day - spectrum and reef frenzy.
RODI icp test is clean

in a span of a week, I’ve lost all of my lps from my old frag system. (Transferred to display with acclimation) Acans, torches. My Trachy and scoly have left their skeletons (haven’t seen this before). Flesh remains healthy - floating around in the water column for several weeks now.
I tried one set of 4 hardier acros, they didn’t make it.
even some bounce mushrooms are struggling and all shrunk.
Kind of at a loss as to what to do.
fish are all well active and healthy.
Thank you in advance for any insight!

this just happened to me; polyp bailout… I’ve always wondered how long the floating heads lived…well I can confirm it’s 3 weeks…
stress event …. hope you forge ahead
P.S …I kept the skeletons of my 4 and 5 year multi headed hammers et …it hasn’t helped

whats your nitrates and phos like? (did I miss them) “safe” = ? tank looks cool and so do the params otherwise
